BMXing had become a huge sport where I lived during the late 70s and early 80s.
I never took part in the BMX racing but I do remember my first BMX bike. I traded an old stereo for it. There was a slight problem with the bike and that was the back wheel which had become an imperfect circle from all of the jumping the previous owner did, but I didn’t care. I road that bike everywhere with a slight bob in the tire. 🙂
